Updates for Backscatter Submissions

Data submitters: SeaBASS submission requirements for backscatter have been updated with more complete guidance, including new fields and metadata to better track provenance from e.g., Hyper-bb, ECO-bb, HS6, AC-S, etc. New submissions should follow these updated guidelines. However, there will be a phase-in period before they are mandatory.

If uploading data for the first time since August 1, 2025:

  • You may see a one-time security warning about the server's host key
  • This is expected due to recent server updates
  • You may safely select Update and proceed

If concerned:

  • Follow standard security protocols
  • Contact the SeaBASS team with questions
